CCS BONDER PASTE, SWL
Short Working Life Epoxy Paste Adhesive For Bonding
CCS Bonder Paste, SWL (Short Work Life) is a two-component, short working life, structural, epoxy paste
adhesive designed for application on vertical surfaces and in horizontal and overhead oriented holes. The
excellent physical properties of the product allow its use in applications requiring resistance to creep and
stress relaxation, maintenance of mechanical properties at high ambient temperatures and high load
bearing strength. Primary applications include general bonding of hardened concrete, masonry and stone to
themselves or each other, steel plate bonding (external reinforcement), bonding applications on vertical and
overhead surfaces and anchoring bolts, dowels and rebar into horizontal and overhead oriented holes in
concrete, masonry or stone. The product is designed for bonding and grouting applications requiring short
set times or for installation and cure at low ambient temperatures. It also may be used as a surface seal in a
pressure injection crack repair process. The working/cure time and viscosity of Bonder Paste, SWL can be
adjusted by blending with the appropriate companion products (see below). The product is non-sag to an
applied thickness of ?inch, bonds to dry, damp and wet substrates and meets the ASTM C 881
requirements for bonding agents in load bearing applications.
